Really enjoying the HVAC course. Looking forward to taking all the free courses that are available.
This inspection on a unit was very revealing.
One of the most important things for an efficient unit is a clean filter. This one as you can tell was very dirty. I explained to the owner that its very important to maintain clean filters to assure the unit wouldn’t be overworking its self. also. I had a licensed HVAC contractor tell me that a dirty filter could cause a 20% decrease in efficiency. For instance, a 15 seer unit could drop to a 12 seer due to a dirty filter.
